Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
If the fluid is low, use DOT 4 brake fluid to refill to the recommended level.

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake line wrench, brake cleaner.
Inspect brake lines, calipers, and master cylinder for leaks.
If leaks are found, replace damaged brake lines or components as necessary.
- For brake lines:
  - Use a brake line wrench to disconnect the line fittings.
  - Replace with new brake line, ensuring proper routing and secure connections.
- For calipers:
  - Remove the wheel.
  - Unbolt the caliper and replace seals or the caliper if leaking.

4. Bleed the Brakes

Tools Required: Brake bleeder kit, clear tubing, container.
After repairs, bleed the brake system to remove air.
- Start at the wheel farthest from the master cylinder (usually the rear passenger side).
- Attach tubing to the bleeder valve and submerge the other end in a container with brake fluid.
- Have an assistant pump the brake pedal and hold it down.
- Open the bleeder valve to release fluid and air, then close it before the assistant releases the pedal.
- Repeat until no air bubbles are seen, then move to the next wheel in order (rear driver, front passenger, front driver).

5. Final Checks

Check brake fluid level again and top off if necessary.
Test the brake pedal for firmness before driving.
